I ended up getting a Ti omni. Now I can't stop. I bought a bunch of old style M's and gave them to friends and family. They all loving them. I now have a new style M for my travel rig and I also purchased a custom stem extra long for the heck of it and I still use my omni. I have retired all my other vapes except for the volcano which I use for party time. Good product for me.
I was thinking of getting a Ti omni. That was until I tried a custom, carbless Ti stem. That's the way to go IMHO.
No fumbling around for the carbhole, and hits so well.
The bonus with vaping is all the ABV. I use it to make coconut oil, for baking, although more often than not I just have a couple of teaspoons in my coffee .
